## Architecture

### Input Validation
- All tools use **Zod** schemas for type-safe input validation
- Schemas defined inline with tool handlers
- Runtime validation with helpful error messages

### Naming Convention
- All tools follow `notion_verb_noun` pattern
- Clear, consistent naming for discoverability
- Examples: `notion_create_page`, `notion_query_database`, `notion_append_block_children`

### File Structure
```
src/tools/
├── index.ts          # Barrel export + central routing
├── pages.ts          # Page operations (7 tools)
├── databases.ts      # Database operations (5 tools)
├── blocks.ts         # Block operations (23 tools)
├── users.ts          # User operations (4 tools)
├── comments.ts       # Comment operations (3 tools)
└── search.ts         # Search operations (4 tools)
```

Each file exports:
- `getTools(client: NotionClient): Tool[]` - Tool definitions
- `handle[Category]Tool(toolName, args, client)` - Execution handler

### Central Routing
`src/tools/index.ts` provides:
- `getAllTools(client)` - Returns all 43 tools
- `handleToolCall(toolName, args, client)` - Routes to appropriate handler

## Notion API Features Covered

### Rich Text Support
- All text fields support Notion's rich_text format
- Helper function `textToRichText()` for simple text conversion
- Supports colors, formatting, links

### Property Types

## TypeScript Compilation
✅ All files compile successfully with `tsc --noEmit`
✅ Full type safety with Notion types from `src/types/index.ts`
✅ No TypeScript errors

## Next Steps
To integrate these tools into the server:
1. Import in `src/server.ts`: `import { getAllTools, handleToolCall } from './tools/index.js';`
2. Replace inline tools in `ListToolsRequestSchema` handler with `getAllTools(this.client)`
3. Replace switch statement in `CallToolRequestSchema` with `handleToolCall(name, args, this.client)`

## Tool Count Summary
- **Total Tools:** 43
- **Target Range:** 35-50 ✅
- **Categories:** 6
- **Lines of Code:** ~57,000 bytes across tool files
